  • Nasogastric tubes are used to aspirate food contents from the stomach or to feed patients who are unable to safely feed themselves.
  • Nasogastric tubes are commonly used in the operating room, intensive care units, home care, and in hospice settings.
  • Prior art nasogastric tubes are frequently used to aspirate stomach contents.
  • aspiration of the stomach contents results in microapirations which can cause nosocomial infections.
  • Laryngeal masks are used to provide ventilation and are commonly used in the operating room and in situations where it is difficult to insert an endotracheal tube.
  • Prior art laryngeal masks and related devices are described in U.S. Patent Nos. 4,351,328 , 4,509,514 , 4, 995, 388 , 5,241,956 , 5,303,697 , 5,355,879 , 5,632,271 , 5,878,745 , 6,631,720 and 6,895,966 and in published international patent application no. WO 1994/02191 .
  • a disadvantage of prior art laryngeal masks is that there is no protection from aspiration into the lungs of gastric contents or saliva regurgitated into the hypopharynx and pharynx.
  • US 3,730,179 A discloses a combination of a resuscitating, aspirating and gastric draining apparatus of unitary construction including a tubular body adapted for insertion into the mouth.

  • the interior of oropharyngeal tube section 16 is known as the lumen.
  • Nasogastric tube section 14 and oropharyngeal tube section 16 are joined together at tube section 18 so as to form a generally "Y" shaped configuration.
  • Tube section 18 is configured to be connected to tube section 20.
  • Tube section 20 is configured to be connected to an external apparatus 21 (shown in phantom).
  • such external apparatus 21 can be a suction apparatus for creating suction within tube structure 12.
  • the aforesaid external apparatus can be a food source for feeding a patient that is unable to feed himself or herself.
  • nasogastric tube section 14 has a sufficient length that allows it to be inserted through the patient's nose 30, through the hypopharnyx region 40 (which is just below epiglottis 42) and into the patient's stomach 50.
  • Nasogastric tube section 14 has opening 60 that is located in the patient's stomach 50.
  • opening 60 functions as a suction intake that effects aspiration of food contents from the stomach.
  • the aspirated food contents travel through nasogastric tube section 14 and into a container (not shown) in suction apparatus 21.
  • opening 60 functions as an output for this food.
  • oropharyngeal tube section 16 is inserted through the patient's mouth 52 and has a length that is relatively shorter than the length of nasogastric tube section 14. Oropharyngeal tube section 16 has suction intake 70. The length of oropharyngeal tube section 16 is such that suction intake 70 is positioned in hypopharynx region 40.
  • suction intake 70 of oropharyngeal tube section 16 sucks in microaspirations and regurgitated material located in hypopharynx region 40 thereby removing such microaspirations and regurgitated material from hypopharynx region 40.
  • suction intake 70 substantially reduces the risk of infection due to aspirations from the stomach 50 moving into the mouth 52.
  • nasogastric tube section 14 and oropharyngeal tube section 16 are fabricated from commercially available flexible, soft plastic material, similar to the material used to fabricate conventional endotracheal tubes.

  • Medical apparatus 100 comprises tube structure 102.
  • Tube structure 102 comprises nasogastric tube section 104, nasopharyngeal tube section 106, and tube section 108.
  • Nasogastric tube section 104 and nasopharyngeal tube section 106 are joined together at tube section 108 so as to form a generally "Y" shaped configuration.
  • Both nasogastric tube section 104 and nasopharyngeal tube section 106 are inserted through the patient's nose 30.
  • Tube section 108 is configured to be connected to tube section 110.
  • Tube section 110 is configured to be connected to an external apparatus (not shown).
  • such an external apparatus can be a suction apparatus such as suction apparatus 21 described in the foregoing description.
  • a suction apparatus produces suction within tube structure 102.
  • tube section 108 and tube section 110 have the same structure and perform the same functions as tube section 18 and tube section 20, respectively, of medical apparatus 10 described in the foregoing description.
  • Nasogastric tube section 104 has opening 160.
  • Nasogastric tube section 104 has a length that ensures that opening 160 is positioned in the patient's stomach 50.
  • Nasogastric tube section 104 performs the same function as nasogastric tube section 14 (see FIG. 1 ).
  • Nasopharyngeal tube section 106 has suction intake 170.
  • Nasopharyngeal tube section 106 has a predetermined that is less than the length of nasogastric tube section 104. This predetermined length of nasopharyngeal tube section 106 allows suction intake 170 to be positioned in the patient's hypopharynx region 40. Suction intake 170 performs the same function as suction intake 70 of oropharyngeal tube section 16 shown in FIG. 1 . When the aforementioned suction apparatus is connected to tube section 110, suction intake 170 sucks in microaspirations and regurgitated material located in hypopharynx region 40 thereby removing such microaspirations and regurgitated material in hypopharynx region 40. Thus, suction intake 70 substantially reduces the risk of infection due to aspirations from stomach 50 moving into mouth 52.

  • suction apparatus 21 described in the foregoing description.
  • suction apparatus 21 When a suction apparatus is connected to tube section 340, suction is produced within tube structure 302 which results in microaspirations and regurgitated material located in hypopharynx region 40 to be sucked into opening 330.

Suction tube 404 further includes tube section 460 that is connected to middle tube section 450 and extends along the rear side of flexible breathing tube 410. Each tube section 430 and 440 has a plurality of suction ports 470 formed on front side 422. Suction tube 404 has end portion 480 that defines opening 482.
